Airworthiness Directives; Airbus Model A330 and A340 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Airbus Model A330 and A340 series 
airplanes, that currently requires repetitive operational tests of the 
override mechanism of the trimmable horizontal stabilizer (THS) to 
determine if the system functions correctly; and corrective action, if 
necessary. This amendment requires replacement of existing flight 
control primary computers (FCPC) with

[[Page 16803]]

improved FCPC's, which would terminate the repetitive operational 
tests. This amendment is prompted by the issuance of mandatory 
continuing airworthiness information by a foreign civil airworthiness 
authority. The actions specified by this AD are intended to prevent 
uncommanded movement of the THS, which could result in reduced 
controllability of the airplane.

DATES: Effective May 4, 2000.
    The incorporation by reference of Airbus Service Bulletin A330-27-
3056, Revision 01, dated May 5, 1998; and Airbus Service Bulletin A340-
27-4061, Revision 02, dated May 5, 1998; as listed in the regulations, 
is approved by the Director of the Federal Register as of May 4, 2000.
    The incorporation by reference of Airbus Service Bulletin A330-27-
3051, dated February 13, 1997; and Airbus Service Bulletin A340-27-
4058, dated February 13, 1997; as listed in the regulations, was 
approved previously by the Director of the Federal Register as of 
January 28, 1998 (63 FR 1909, January 13, 1998).

ADDRESSES: The service information referenced in this AD may be 
obtained from Airbus Industrie, 1 Rond Point Maurice Bellonte, 31707 
Blagnac Cedex, France. This information may be examined at the Federal 
Aviation Administration (FAA), Transport Airplane Directorate, Rules 
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of 
the Federal Register, 800 North Capitol Street, NW., suite 700, 
Washington, DC.

FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 98-01-15, 
amendment 39-10277 (63 FR 1909, January 13, 1998), which is applicable 
to certain Airbus Model A330 and A340 series airplanes, was published 
in the Federal Register on December 14, 1999 (64 FR 69674). The action 
proposed to continue to require repetitive operational tests of the 
override mechanism of the trimmable horizontal stabilizer (THS), and to 
require replacement of existing FCPC's with improved FCPC's, which 
would terminate the repetitive operational tests.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    None of the airplanes affected by this action are on the U.S. 
Register. All airplanes included in the applicability of this rule 
currently are operated by non-U.S. operators under foreign registry; 
therefore, they are not directly affected by this AD action. However, 
the FAA considers that this rule is necessary to ensure that the unsafe 
condition is addressed in the event that any of these subject airplanes 
are imported and placed on the U.S. Register in the future.
    Should an affected airplane be imported and placed on the U.S. 
Register in the future, it will require approximately 1 work hour to 
accomplish the operational test required by AD 98-01-15, and retained 
in this AD, at an average labor rate of $60 per work hour. Based on 
these figures, the cost impact of the operational test on U.S. 
operators is estimated to be $60 per airplane, per test cycle.
    It will require approximately 2 work hours to accomplish the FCPC 
replacements (or 9 work hours if the FCPC on-board replacement modules 
have been replaced or reprogrammed), at an average labor rate of $60 
per work hour. Required parts will be provided to the operator at no 
charge. Based on these figures, the cost impact of the FCPC 
replacements required by this AD on U.S. operators will be $120 or $540 
per airplane.
    Accomplishment of the FCPC replacements required by this AD will 
allow operators to terminate the repetitive operational tests required 
by AD 98-01-15, thereby offsetting the cost of the actions required by 
this AD.

Regulatory Impact

    The regulations adopted herein will not have a substantial direct 
effect on the States, on the relationship between the national 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a 
significant economic impact, positive or negative, on a substantial 
number of small entities under the criteria of the Regulatory 
Flexibility Act. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
